Description

Improved High Voltage Generator with Long Type Coil Fixture and Double Magnet Rotor

The present invention relates to a high voltage generator (hereinafter referred to as " long type high voltage generator ") having an elongated coil fixture in the longitudinal direction. More specifically, the present invention is a nonmagnetic internal magnetic rotating body in which even-numbered N-pole and S-pole internal permanent magnets are alternately inserted at regular intervals along the circumferential direction, The inner magnet rotating body being fixed by penetration; Wherein a plurality of winding coils are inserted at regular intervals along the circumferential direction of the coil fixing body so as to surround the inner magnet rotating body in a radial direction and spaced apart by a predetermined first separation distance Wherein the winding coils comprise a coil wound without a bobbin and the winding coils are arranged so as to be wholly aligned with respect to each other in a cross section of the winding coils perpendicular to the axial direction of the coil coils, ; Wherein the outer permanent magnet body is a nonmagnetic outer permanent magnet body which surrounds the coil fixing body in a radial direction and is spaced apart by a predetermined second distance from the outer permanent magnet body so that the even outer permanent magnets correspond to the even inner permanent magnets, Wherein the inner permanent magnets and the inner permanent magnets are alternately inserted at regular intervals along the circumferential direction of the inner magnet, and the opposite sides of the inner permanent magnet are opposite in polarity to each other, An outer magnet rotating body fixedly coupled to the rotating body; And a supporting structure including a bearing structure that fixes the coil fixing body and supports the rotary shaft so that the rotary shaft is freely rotatable while the first separation distance and the second separation distance are maintained, .

Conventional air-core generators generate electricity by electromagnetic interaction between a rotating body and a fixed body, and take a method of achieving high efficiency of power generation by removing an iron core.

As a coil used in an actual generator, an iron core type coil in which an iron core is inserted as a core of the coil is used more than an air core type coil simply winding a wire. An iron core refers to a main component having magnetic properties made of an iron-based metal. Such an iron core is used for the purpose of increasing the inductance of the coil. This is related to the coefficient of permeability (specific magnetic permeability) among the characteristics of the core. In the case of an air core type coil, the core is air, so μ = 1. On the other hand, in the case of an iron core, mu is several tens or more, and in some cases, up to 10,000 can be obtained, so that a high inductance can be obtained even with a small number of coils and small coils. For example, the field-type generator disclosed in U.S. Patent No. 5,930,392 uses a coil wound around a toroidal core.

On the other hand, air core type coils have a disadvantage in that the permanent magnet linear type synchronous motor has a magnetic gap much larger than that of the iron core type coils and the thrust density is lowered. On the other hand, detent force force is removed fundamentally, the thrust ripple hardly occurs, and the vertical force is small, so that the control performance is excellent.

However, since a constant circulating magnetic force is not formed in the air core type coil, it is necessary to prevent the voltage drop of the generator using the same. In the low voltage power generation, since the charging voltage of the air core type coil is low, A voltage drop occurs. In order to solve this problem, the present invention adopts a method of generating a high charging potential at the coil portion by minimizing the voltage drop by generating a high voltage.

On the other hand, the technique disclosed in Korean Patent Registration No. 10-0683472 is disadvantageous in that the coil is wound around the bobbin to separate the coil fixed by the thickness of the bobbin and the rotating magnet, Thereby eliminating such a technical problem. Another disadvantage of this prior art is that the stationary coil support plate is fixed to the bottom surface of the coil plate and fixed, and there is a possibility that the generator will be severely shaken during the rotation operation of the generator. This is because there is a risk that the magnet will come off.

The technique disclosed in Korean Patent Publication No. 10-2013-002013 relates to a plate-type generator in which magnets are arranged on a magnet rotating plate. Since the coil fixing plate of this plate-type generator is provided with the same number of winding coils as magnets, As shown in the detailed description and the drawings, it is suitable for low-pressure single-phase power generation but has a disadvantage that it is not suitable for high-voltage three-phase power generation. Another disadvantage of this prior art is that when the plate-type generator is operated at a low voltage, a voltage drop may occur depending on the load power when the load is applied to the generated power as in the conventional air-conditioner generator.

The inventor of the present invention intends to provide a detailed technical content of the structure and material according to the present invention which can obtain power energy with high output power by solving the problems of these prior arts and which includes a plan for reducing the size and weight of the generator .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

1A is a cross-sectional view of a long type high voltage generator according to an embodiment of the present invention, FIG. 1B is a cross-sectional view passing through the center of a long type high voltage generator of FIG. 1A taken perpendicularly to the longitudinal direction, FIG. 1C is a long type high voltage Fig.

FIG. 2A is a longitudinal cross-sectional view of the inner magnet rotating body included in the long type high voltage generator according to the embodiment, FIG. 2B is a cross-sectional view passing through the center of the inner magnet rotating body taken in a direction perpendicular to the longitudinal direction, Is a partial cross-sectional perspective view of the inner magnet rotating body of Fig.

1A to 1C and FIGS. 2A to 2C, a long type high voltage generator according to the present invention includes a non-magnetic body 21 in which an even number of N pole and S pole inner permanent magnets 21 are alternately inserted at regular intervals along the circumferential direction And a rotating shaft 10 is fixed to the center of the inner magnet rotating body 20 through the inner magnet rotating body 20. The rotating shaft 10 is integrated with the inner magnet rotating body 20, and the outer magnet rotating body, which will be described later, is also connected to the inner magnet rotating body 20 so as to constitute a double magnet rotating body.

For example, four alternating N pole permanent magnets and S pole inner permanent magnets 21 may be inserted into the inner magnet rotating body 20 at intervals of 90 degrees along the circumferential direction. The same applies to external permanent magnets inserted into the whole.

In one embodiment of the present invention, the nonmagnetic material used in the inner magnet rotating body 20 may be a processed ceramic to be described later in more detail, which is used as a nonmagnetic material in an outer magnet rotating body to be described later This is the same.

Here, the inner permanent magnet 21 in the longitudinal direction can be mounted in the insulating member of the inner magnet rotating body 20. At this time, since the inner permanent magnets 21 inserted in the inner magnet rotating body 20 are configured such that the poles thereof are alternated, the opposing inner permanent magnets inserted in the inner magnetic rotating body 20 are arranged so as to have the same polarity . For example, the outer pole of the inner permanent magnet inserted into the inner magnet rotating body 20 is an S pole so as to face the outer S pole of the inner permanent magnet inserted into the inner magnet rotating body 20, and the inner magnet rotating body 20, the outer pole of the inner permanent magnet inserted to face the outer N pole of the inner permanent magnet inserted into the inner permanent magnet becomes the N pole. Preferably, the inner permanent magnet 21 may be mounted so as to be exposed to the outer surface of the inner magnet rotating body 20. [ In other words, this structure can be said to be a structure in which a longitudinal long-type permanent magnet is located at the center of the armature and a field of the permanent magnet rotation is arranged in the circumferential direction such that the S-pole and the N-pole face each other.

9 shows an example of how the individual magnets are superimposed to form the inner permanent magnet 21 and the outer permanent magnet 15 to be inserted into the inner and outer magnet rotating bodies 20 and 16 according to the present invention Fig.

Representative strong magnets used in the individual magnets (indicated by N / S poles) shown in Fig. 9 include neodymium magnets and samarium cobalt magnets. All of them have a strong magnetic force of 3,000 Gauss or more, but it will be understood by a person skilled in the art that the characteristics such as the temperature characteristics and the intensity are different from each other and the characteristics can be compared and a suitable magnet can be selected according to the application.

Among them, neodymium magnets are the most powerful magnets that exert 5,500 gauss of magnetic force. However, they have poor temperature characteristics and their magnetic force can be weakened when they are used at temperatures of 60 to 80 degrees Celsius. However, it is possible to utilize a neodymium magnet having a heat resistance of 220 degrees Celsius, that is, a high-temperature neodymium magnet, through special processing. On the other hand, the samarium cobalt magnet has a magnetic force of 2,000 ~ 3,500 gauss which is 10 ~ 20% weaker than the neodymium magnet, but its temperature characteristic is excellent and it does not lose its magnetic force even at a high temperature of 350 degrees Celsius maximum.

Neodymium magnets through special machining may be used, but in order to obtain a stronger magnetic force, the present inventors have found that by arranging and compressing several neodymium magnets or samarium cobalt magnets together in a thin stainless steel case as shown schematically in FIG. 9 The obtained magnet was used.

3A is a longitudinal cross-sectional view of the coil fixing body included in the long type high voltage generator according to the embodiment, FIG. 3B is a cross-sectional view passing through the center of the coil fixing body of FIG. 3A taken perpendicularly to the longitudinal direction, 3c is a partial cross-sectional perspective view of the coil fixture of Fig.

1A and 3A to 3C, a high voltage generator according to the present invention includes a non-magnetic coil fixing body (not shown) radially surrounding the inner magnet rotating body 20 and spaced apart by a predetermined first separation distance Wherein at least three winding coils (18) are inserted at regular intervals along the circumferential direction of the coil fixing body (17), and the winding coils (18) are wound in a state of being wound without a bobbin And the wound coils are arranged so as to be wholly aligned with each other in the cross section of the winding coils (18) perpendicular to the axial direction of the coil fixing body (17). The winding shaft of the winding coil unit 18 may be configured to face the central axis of the coil fixing body 17 so that the magnetic flux varying by the inner and outer magnet rotating bodies can pass through the winding coil unit 18 Is apparent to those of ordinary skill in the art.

The number of the inner permanent magnets 21 inserted into the inner magnet rotating body 20 described above and the number of the outer permanent magnets 15 to be inserted into the outer magnet rotating body to be described later may be four, 12, 16, 20, and so on. In this case, the long type high-voltage generator generates power of 4 poles, 8 poles, 12 poles, 16 poles, 20 poles, 18 may be three in the case of the four poles, six in the case of the eight poles, nine in the case of the twelve poles, twelve in the case of the sixteen poles, and fifteen in the twenty poles.

In other words, when the electric power generated by the long type high voltage generator according to the present invention is configured to be three phases, if the number of the inner and outer permanent magnets 21 and 15 is an even number n, The magnets 21 and 15 are arranged at N / S poles according to the number of poles at intervals of 360 / n along the circumferential direction, and the winding coils 18 are 3n / And can be arranged according to the number of the odd-numbered poles. As the number of poles n increases, the outer diameter of the coil fixture and the inner and outer magnet rotors may become larger.

On the other hand, when the power generated by the long type high voltage generator according to the present invention is configured to have a single phase, the inner and outer permanent magnets 21 and 15 and the winding coils 18 may be disposed differently from the above- Of course.

As one example, the three or more wound coil coils 18 may be three wound coil coils, and may be inserted into the coil coils 17 at intervals of 120 degrees along the circumferential direction.

Preferably, the wound coil included in the wound coil unit 18 may be an insulated coil. In the present invention, various insulators may be used to reach a high voltage without causing a short circuit of the coil.

Here, 'insulator' is a term that refers to a nonconductive material that interferes with the movement of electric charge. Even such an insulator can flow a current in an alternating current other than direct current. Since an insulator also has a dielectric constant, if an alternating current is applied, the displacement current or the polarization current flows in proportion to the magnitude of the dielectric constant. The reason why electromagnetic waves can travel into the insulator air is the existence of such a polarization current. In short, an insulator having a very good insulating property refers to a dielectric material having an extremely small dielectric constant.

10 is a cross-sectional view of an exemplary winding coils 18 according to the present invention.

As one of the methods of forming the insulating coil in the present invention, a quartz glass coating may be applied to the copper wire to prevent the coil from being burned even under a high voltage. This is because the glass- And is an insulating coil 101 which is wrapped around a copper wire and sealed. Here, the polyester mixed material is melted at a high temperature and is coated with a glass coating of at least 0.020 mm to a maximum of 0.135 mm on a copper wire through an extrusion nozzle, so that it is referred to as an optical fiber glass insulation. It is a polyester mixed glass quartz glass coating formed on a copper wire, and it is advantageous that the glass coating is not broken even at 300 degrees Celsius for durability, insulation strength, mechanical strength, flexibility, moisture resistance, chemical resistance and heat resistance.

Since such a glass insulation can be wound to a practical thickness by holding a coil with a thin thickness, the utilization of the glass insulation is very high. Therefore, the leakage potential does not occur until a high voltage of 66 kV and the insulation is not destroyed. ≪ / RTI > As a result, the table showing the relationship between the characteristics of the copper wire forming the insulating coil, the thickness of the glass film, the insulation of the insulating coil, resistance, current, and voltage is shown in Table 1 below.

As shown in Table 1, the insulation coil passed the insulation breakdown test for a small generator coil of 3.3 to 14 kV, and it was tested for a large generator of 25 to 35 kV, 35 to 66 kV, and 66 to 220 kV as well as a medium- As a result of the insulation breakdown test on the coil, it will be appreciated by those skilled in the art that the insulation coil is suitable for use in the long type high voltage generator according to the present invention. On the other hand, The copper varnish film is formed by coating an insulating varnish having various characteristics depending on the use of a copper wire having a good electrical conductivity and molding it at a high temperature several times. Such a polyester varnish film has a heat resistance limit of 220 degrees Celsius, The chemical property is disadvantageous in that it is excellent in oil resistance and solvent resistance, but is weak in film-forming property and in flexibility. In addition, the withstand voltage is about 10 kV, and the high-voltage insulation treatment of 10 kV or more requires a separate insulation film. If the thickness of the insulation film is increased, the coil volume becomes too large and an efficient winding method can not be achieved. In order to increase the withstand voltage, the volume of the coil is increased, so it is suitable for low voltage and it is used in winding method of transformer.

The glass coating insulation according to the present invention exhibits the characteristics shown in Table 1, so that the cross sections of the coils are aligned to be hexagonal (a) or square (b) When the winding coil unit 18 is constructed by the winding method, the magnetic force lines are not distorted at the time of high-voltage power generation, and a current higher than the rated load current value can be prevented from flowing to the coils when a load is applied to the coils.

When a coil is wound around a bobbin for winding using a conventional enameled copper wire or the like in a conventional manner without taking such a winding method, a magnetic current line between the coils is distorted at the time of low-voltage power generation so that a current higher than the rated current flows through the coil, However, at high voltage power generation, the coil insulation breaks down and a short circuit occurs due to an interlayer short circuit. Also, in the case of low-voltage power generation, when the coils are wound without being aligned, losses due to resistance are generated as described above due to the induced electromotive force between the coils. In short, it is a good way to increase the efficiency of the generator by adopting a winding system that is fully aligned for both low voltage and high voltage.

Referring again to Fig. 10, the winding coils 18 may further include an insulator formed by an epoxy carburization insulator 102 at the periphery of the entire wound coil. This is because, when a corona is generated between the inner magnet rotating body 20 and the outer magnet rotating body 16 due to the high voltage that can be generated in the insulating coil, the coil may be damaged due to the arc of the magnet and the magnet. And the wound coil needs to be sealed with a mold, for example, a pressurized carburizing insulation-treated mold in order to secure high-voltage power generation. In this regard, it is not necessary to carry out the secondary insulation of the mold type in the low-pressure power generation, but in the high-voltage power generation, the wound coil must be subjected to the secondary insulation treatment.

Insulating materials that can be used for the high voltage generator of the present invention include the following.

First, the glass laminate is laminated with a thin resin sheet and heated under pressure. The resin is mainly made of thermosetting resin (phenol, epoxy, silicone, polyester, etc.) and various reinforcing materials (paper, cotton fabric, glass fiber fabric, non- , It has high heat resistance, excellent mechanical strength and electric insulation and is widely used as an insulating material, a sheathing material, a reinforcing material, and the like. Among them, flame retardant epoxy glass laminate (bakelite) and epoxy plate are typical, and a thin reinforcing sheet of a woven / non-woven form is impregnated with a resin and a thickness chamfering is performed after molding to obtain a desired thickness. The flame-retardant epoxy glass laminate has a volume resistivity of 10-20? Cm and an impact strength of 10 Kgcm / cm or more with an azod or notch. The shielding effect is maintained for a long time, and the mechanical and electrical strength characteristics are excellent. Further, the electrical insulation of the flame-retardant epoxy glass laminate sheet is 100 (KV / mm) or less at low and high pressures, the heat resistance is excellent at 180 degrees Celsius or less, and the abrasion resistance is good.

Next, ceramic is used as a product that is formed by molding non-metallic inorganic compound into raw material and subjected to heat treatment process. Ceramic is a product made by processing or molding a non-metallic or inorganic material at high temperature. There are various types of ceramic, such as a course ceramic using the raw material as it is, and a fine ceramic processed by refining. The characteristics of such ceramics are such that they make sound when they are insulated, stored or electricity, they sense humidity, oxygen content, they are resistant to high heat, they are light and have high strength, and their applications are low voltage, high voltage , Electrical insulators such as ultra-high voltage, magnetic, mechanical, chemical, optical, and biotechnology.

Unlike metals and plastics, such ceramics do not melt or decompose until they reach a very high temperature. In other words, it is excellent in heat resistance or fire resistance and is utilized in various fields as a heat resistant material such as a blast furnace and a stern part of a space ship. This is because, as mentioned above, it has a characteristic that it has a high melting point, is hardly oxidized at a high temperature and is safe at a high temperature. Ceramics and glass are used as insulating materials because ceramics and glass have almost no electricity, and when combined properly, materials with lower conductivity and higher conductivity than insulators can be made.

Such electrical properties of ceramics are utilized in heat exchangers, solar cells, fuel cells, thermoelectric devices, gas turbines, gas materials, optical materials, piezoelectric devices, semiconductors, and dielectric materials. Electrical insulation can maintain insulation up to 746 kV from low voltage to very high voltage. It has high heat resistance and its tensile strength does not change even at 1400 degrees Celsius. The mechanical strength of the ceramic is excellent, but it is fragile. Despite these drawbacks, ceramics are still in widespread use, and their properties have been continually improved.

In the long type high voltage generator of the present invention, the use of the insulator may be different depending on the use, and in particular, the application may be different depending on the voltage. Actually, in the test of the long type high voltage generator of the present invention by the present inventor, Beckrite was used as an insulator up to 3.3 kV to 55 kV, and it is understood that a ceramic can also be used as an insulator in the range of 3.3 kV to 345 kV .

According to this embodiment, the upper limit of the output voltage may increase by 60 kV as the number of coil fixtures increases by one. It is to be understood, however, that the output voltage according to the number of coil fixing bodies is not necessarily limited to such a range.

Like the internal permanent magnet 21 mentioned above, the external permanent magnet 15 can be mounted in the insulating member of the external magnet rotating body 16 here.

Preferably, the outer permanent magnet 15 may be mounted so as to be exposed to the inner surface of the outer magnet rotating body 16.

As the distance between the winding coils 18 and the inner or outer permanent magnets 21 and 15 increases, power generation efficiency decreases. By reducing the minimum distance, the generator can be miniaturized and power generation efficiency can be improved. However, In order to prevent the loss of kinetic energy due to the contact due to the shaking, the processing balancing is performed so that the error of the rotating body is within ± 0.3% so that the noise and the vibration are minimized at high speed, and the inner magnet rotating body 20 and the coil fixing body 17) and the minimum distance between the outer magnet rotating body and the coil fixing body.
